SPRING-MOTORDRIVEN TABLE-FAN.

Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed January 26, 1910. Serial No. 540,194.

spring motor driven table fan, the object ot the4 mvention bemg to prov1de improved means for revolving fans supported on a reif'olving head or support. with improved means for traiisn'iitting motion from a lspring to impart rotary motion to the 'fans and to the head or support.

A Jfurther object is to provide an improved arrangement ot gears. an improved casing inclosing them, an improved means for winding the sprine, an improved ball bear .ing mounting for'the head and improved mounting for the fan blades which permit them to be. turned to any de ired angle, all ot which results in a device ot' `simple. inexpensive. ci, lstruetiou. ornamental and attractive in appearance. and strong and durable in use.

With these and other objects in view, the invention consists in certain novel iieatures ot' construction and eombinations and arrangementsl of parts as will he more fully hereinafter described and pointed out in the claims.

ln the accompanying drawings, ltigure 1, is a view in vertical longitudinal section illustrating my improvements. Fig. 2, is a top plan view. l"ig. tl. is a fragmentary view showing the Al'an blade mounting. Fig. 4, is a. view in eros-s sect ion on the line lm-4 of Fig. 1, and Fig. 5, is a lraganentary view in vertical section illustrating the spring winding mechanism.

1 represents a. casing preferably ol' the. shape shown but l do not, oi course, limit' myself to any limrtienlar shape. horiaontal partition 2 is secured in the easing by means of screws il and dividesl the easing into an upper gear 'chamber -l and a lower spring chamber 5. the latter closed h r a bottom plate t3 secured in place by serews 7.

8 represents a vertical shalt. located een-v t'rally in the spring chamber 5, having a thrust bearing 9 in bottom plate t3 and proA jecting up through partition 2 into gear chamber 4. A sleeve 10 is keyed to shaft. 8

in chamber 5 and a large gear wheel 11 is secured to the upper end et the sleeve 1 0 and is connected by a series ot' rods 12, with disk 12l tiXed to the lower end of the sleeve forming a spring casing. and 123 represents a spring secured at its inner end to sleeve 10, wound on the sleeve, and secured at its other end to one ot the rods 12.

To wind the spring, a short shaft 14 projects through the 'all of chamber 5 and is made. angular on its outer end for the reception of a key 15, shown in dotted lines in Fig. 5, to turn the same. A beveled pinion 1li, secured on the inner end ot' this shaft 14 meshes with a beveled pinion 17 fixed to a spur gear 1S and both supported on a short shalt 19 secured in partition 2, and said spur gear 1S meshes with large gear 11. so that the turning of shaft 14 serves to transmit rotary motion to the gear casing to wind the spring. To prevent any retrograde movement of the spring case, a zatchet wheel 2() is secured on shaft bland is engaged by a pivoted dog 21` connected to a bracket 22 secured to casing 1.

In gear chamber 4, in line with shaft 8 and projecting up through the top of casing 1 is a shaft 23 which is provided at its lower end with a pin 24, projecting into a socket 25 in the upper end of shaft 8, holding` the shafts against lateral displacement but permitting independent rotary movement. Shafts 2G and 27 are also located in chamber 4 at opposite sides of shaft 23 and are supported at their ends in the top of casing 1 and in partition 2. On shaft 8, in chamber 4, a large gear 2S'and a simili pinion 29 are keyed. The large gear 28 meshes with a small pinion 30, keyed to shaft 26 and a large gear 31 keyed on shaft 2t meshes with a small pinion 32, keyed on a sleeve 33. loose 011 shaft 23. A large. gear 34, keyed on sleeve 33, meshes with a small pinion 35, keyed on a sleeve 3U, loose on shaft 2G and a large gear 37,- keycd on sleeve Btl, meshes with ay small inion 38, keyed on a sleeve 39. loose on sha t A large gear 40, keyed on sleeve 39 meshes with a small pinion 41, keyed on a sleeve 42, loose on shaft 26 and a large gear 43, keyed on sleeve 42, meshes with a small pinion 44, keyed direetly'to shaft 23, so that the speed ot shaft is greatly increased over the speed of shaft 8. The small pinion 29, on shaft 8, meshes with a large gear 45, keyed on shaft 27 and a sinall pinion Litt. keyed on shaft 2i", meshes With-a large gear Il?, keyed on a sleeve 48, loose on shaft 23, and projecting up through the top of casing l. the upper end of this sleeve 48, is keyed in a central sleeve or collar 49, in a rotary head 50, having` a bottom 5l held in place on shaft 23 by a clamping collar The bottom 5l and top of easing l are provided with circular runways for balls 53, reducing friction and noise and resulting in an easy turning` head. A partition 54 kis secured iii. head 50 and through Which shaft 23, projects and has a large beveled gear secured on its upper end ineshini1 with beveled pinions 56 secured on i i l l i i i fan shafts supported in bearinofs v' at opposite sides of the head 50. ySleeves 5S are secured on shafts 57, by means of screws 59, and these sleeves 58 are provided with radial lugs (50 to receive sleeves or collars (il at the inner ends of the fan blades 62 and thumb screws G3 are provided in said sleeves or collars til and are adapted to engage lugs 60, to loch the blades at the ldesired angle of adjustment.

In operation, it will be observed that while the fans are revolved the head 5() is slowly turned to blow the air in all directions.

The device is especially adapted for use on dining tables but is also adapted for other uses and I do not restrict myself to the precise details set forth but consider myself at liberty to malte such changes and alterations s fairly fall `within the spirit and scope of the appended claims.

Having thus described iny invention what l claim as new and desire to secure by lietiA ters Patent is :T

l. in a fan, the combination with a easing, of a rotary head on the casing, fans on said head, a spring,- driven shaft in the cas ing, a fan driving shaft in the casing projecting up into the hcad, means for transshaft to the fans. a train of gearing` connecting the spring' driven shaft and fan driving shaft, a sleeve keyed to the head and projecting into the casing, and ay train of gearii'ig transinitting` i'i'iotion from the spring' driven shaft to said sleeve.

2. In a fan, the combination with a. casing, of a rotary head on the casing, fans supported at oiiiposite sides of the head, a l

shaft projecting through said head and into the casing, and around which said head turns, a large gear on the upper end of said lshaft, fan driving pinions meshing' with said large gear, a sleeve secured to the head located around said shaft, and projecting into the casing, a spring, and gearing between said spring, and said shaft for revolving the fans, and between said spring and said sleeve, for turning the head, substantially described.

E5. In a fan, the combination with a ing, of a rotary head on the casing, fans at opposite sides of the head, a shaft projecting` through the head and into the casing, de-

vices at the upper end of said shaft for turning the fans, a sleeve secured to said head and located around said shaft, and projecting into the casing, gears on said shaft and said sleeve in the casing, shafts in the easing parallel with' the lirst mentioned Shaft, a gear on one'of said shafts engaging with the gear on the first mentioned shaft, a ,gear

on the other of said shafts engaging the gear on the sleeve, and a springr in said casing transmitting motion to both of said last'. mentioned shafts, substantially as described.

4. In a fan, the combination with a casing, of a rotary head on the easing, fans at opposite sides of the head, a shaft projectinpy through the head and into the fasing, devices at the upper end of said shaft for turning' the fans, a sleeve secured to said head and located around said shaft, and projecting into the casing, gears on said shaft and said sleeve in the casing, shafts in the casing' parallel with the 'lirst mentioned shaft, a ALear on one of said shafts engagingi with the gear on tho first mentioned shaft, a gear on the other of said shafts engaging the gear on the sleeve, a spi-ingr in said easing,a short shaft turned by said spring', `gears connecting;- said short i i shaft with the two last mentioned shafts, initting rotary motion from the tan drivingf ,l

and means for winding said spring', subst antially as described.

ln testimony whereof I have signed my naine to this sl'ieeieation in the presence of` two subscribing' Witnesses.
